Patrick Clancy in his own words: Top takeaways from grieving father's first interview

Patrick Clancy begged for just one of his children to survive, held baby Callan as he died in his arms and revealed why he forgave Lindsay after she killed their three children.

Speaking with correspondent Ross Douthat on CBS News' "60 Minutes," the grieving father shared new details about his children's final moments, what Lindsay told him about the killings and the online attacks he says are hurting their legacy.

The interview aired after Lindsay's triple-murder trial ended in a mistrial.

Her attorneys argued she was suffering from postpartum psychosis and was not criminally responsible, while prosecutors maintained she knew what she was doing.

From his desperate plea at the hospital to the online claims that followed the mistrial, Patrick described how the tragedy has shaped every part of his life.

Doctors had restored the baby's heartbeat, and Patrick told Douthat he began imagining the life he could still give his youngest child.

"I remember that night, I really thought there was a chance that Callan would live," Patrick said.

"And I remember just thinking, ‘Just give me one.

Just give me one kid,’" he continued.

"And I would raise him as best I could, and I would give him the best life I possibly could.

And I'd tell him about his brother and sister." Patrick said that hope faded when he reached Boston Children's Hospital and saw the look on a doctor's face.

Callan's heart continued beating for four days.

Patrick became emotional as he recalled apologizing to his son and spending his final moments beside him.
